isnt the bore price the same for what ever size?
thanx homie but im on the west coast ans the shipping charges would be intense. it would make more sense to get a crate engine at that point. any one in the so cal area???

I know there's a combo to make a 409 small block, I don't know the bore/stroke off hand though, and I don't have any of my books here. but if it's an impala you could run 409 flags and then when people laugh at you you could shut them up. :biggrin:
took me way too long to figure out, but you can use a stock 400 crank and stock rods, with stock pin height 040 400 pistons.

stock 400 is 4.125Sx3.75B

.040 over = 4.165 bore,

(2.0825 ^2) X pi x 3.75 x 8 = ~408.7 ci

I'm fully going to build one one day now that I know it's just a 040 over 400. I bet there's hundreds of them out there that the owners don't even know they're 409s.
